ETX 70 EC focuser fitting |
| The Meade ETX series of telescopes are particularly troublesome when it comes to getting the system in focus, as the focusing knob is mounted at the back of the telescope, and is difficult to reach when at high angles. The ETX70 Scopes have a 3.5mm focussing shaft. The frameless version of the motor, sits on the shaft and nestles loosely against the side of the telescope. |
|
|
| The system moves in and out with the focusing shaft as the system operates, but the side of the telescope prevents rotation of the motor. The motor is small enough to allow high elevations to be observed without obstructing the telescope. The system is necessarily a loose fit, which does lead to a very slight lag on direction change when focussing. |
 |
| The motor system is small enough to allow the telescope to be positioned vertically, without removing the motor - useful for high elevation gazing, where the Meade focus knob cannot be easily reached, or for packing the system away. |
 |
| The existing focus knob may be removed with a small Allan (Hex) key, and the 3.5mm shaft coupler on the focuser slots on in place of the original Meade focus knob. |
